How to disable base color in title?

Also not sure why you would want to do this, but here you go

.topic-list-main-link a.title, .topic-list .main-link a.title, .latest-topic-list-item .main-link a.title {
    color:var(--primary) !Important;
}

I agree with everybody above, thsis would be very annoying to me as an end user but you do you.
